Real-time stream processing has become a critical component of modern data-driven applications. Apache Pulsar is an open-source distributed messaging system that provides seamless horizontal scalability and low-latency processing of real-time data streams. Spring Boot is a popular Java framework that simplifies the process of building and deploying production-grade applications. In this article, we will explore how to use Apache Pulsar and Spring Boot for real-time stream processing.
Getting Started With Apache Pulsar
The first step in building a real-time stream processing application with Pulsar is to set up a Pulsar cluster. A Pulsar cluster consists of one or more brokers that handle incoming data streams and route them to the appropriate consumers. Pulsar provides a simple and straightforward way to set up a cluster using the Pulsar CLI tool.
